Here is one of the results from the Perito Moreno CPCD last month in Argentina. What you’re seeing here are ice spires on the front face of the glacier, which is shaded, and the river of ice trailing behind which is in brilliant sunshine. The weather was partly sunny (or partly cloudy – it all depends on your disposition, I suppose) so I stood in the same place for quite a while and waited for the sun to appear and reappear from behind clouds as I experimented with different lighting conditions. Of the four variations – all sun, all shade, front glacier face in sun with the background shaded and front glacier face in shade with background in sun – I preferred the last choice, the result which you see here.
I can’t stress enough the importance of light and how it reveals the landscape. For example, with the lighting option where the entire scene was equally sunlit, there was not enough contrast between the foreground spires and the background. The same goes for the all-shade option. This lighting option provided the maximum drama that was available to me.
